I worked in sunmy Calif in the San Jose Assembly plant, Vin code R , from the old Richmond Calif factory. I usually spent 2 to 3 weeks in Dearborn reviewing the new models for assembly feasabiliyty and they had a spot on the blue prints for my signiture.

You must have interesting photo albums and memorabilia of the period Tim. The vin i have is 7FO1C....... so that would predate your time at Richmond and Dearborn. If you have any pics of the plant back then you want to put out there i would be happy to have a look
Cheers
